Description

Technical Field

[0001] The utility model belongs to the technical field of mice, and in particular relates to a bottom plate foot pad structure and a mouse using the structure. Background Art

[0002] The mouse is an extremely important human-computer interaction device in computer applications. It can simplify command input. With the increasing number of computer applications in various fields of work and life, long-term mouse operation is becoming more and more common. In order to make the mouse operation easier, a foot pad is usually installed on the bottom of the mouse. Traditional mouse foot pads have a large coverage area, such as multiple strip-shaped mouse foot pads pasted on the bottom of the mouse, or modular mouse foot pads almost covering the entire bottom surface of the mouse. Since the contact surface of the bottom of the mouse is not an absolute plane, it is impossible to keep the foot pad and the work surface in stable contact. Therefore, the resistance center of the mouse will change greatly during the movement process, and there will be an uneven movement when operating the mouse.

[0003] Therefore, a mouse foot pad with a reasonable layout is needed to solve the above problems. Utility Model Content

[0004] The utility model aims at the defects of the prior art and provides a bottom plate foot pad structure and a mouse adopting the structure.

[0005] A base plate foot pad structure, comprising a connecting plate; the connecting plate has a stable structure extending outward, a mouse is installed on the top of the connecting plate, and an area for installing the foot pad is provided at the bottom of the connecting plate; an opening is provided on the connecting plate for a mouse displacement sensor to receive optical energy so as to work normally;

[0006] The outer contour of the bottom projection of the connecting plate has three points, at least one of which is located on the outer contour of the bottom projection of the stable structure, and the ratio of the area of ​​the triangle formed by the lines connecting the three points to the outer contour area of ​​the bottom projection of the connecting plate is greater than 0.5.

[0007] Furthermore, the base plate foot pad structure also includes a foot pad set, which is installed on the bottom of the connecting plate, and the bottom of the foot pad set is in contact with the working surface; there are multiple foot pad sets, and each foot pad set has one or more continuous or discontinuous foot pads; the bottom of the connecting plate has multiple support areas, and the rectangle with the smallest area of ​​the bottom surface projection of all the foot pads in the foot pad set is the support area of ​​the foot pad set; the bottom of the connecting plate has 3 mutually exclusive foot pad sets, each of the foot pad sets corresponds to 1 support area, and the size of each support area is less than 30mm×30mm.

[0008] Furthermore, the size of each supporting area is smaller than 20 mm×20 mm.

[0009] Furthermore, the ratio of the area of ​​the triangle formed by the connecting lines of the three points to the outer contour area of ​​the projection of the bottom surface of the connecting plate is greater than 0.7.

[0010] Furthermore, the ratio of the area of ​​the triangle formed by the connecting lines of the three points to the outer contour area of ​​the projection of the bottom surface of the connecting plate is greater than 1.

[0011] Furthermore, the foot pad is made of wear-resistant and smooth material.

[0012] Furthermore, the foot pad is made of Teflon material or ceramic material.

[0013] Furthermore, a circular area with a radius of 30 mm and the three points as the center is called an edge area; and the three support areas intersect with the three edge areas respectively.

[0015] Furthermore, the connecting plate is provided with a plurality of mounting holes; and the bottom of the mouse body is provided with threaded holes matching the mounting holes of the connecting plate.

[0016] The beneficial effects of the utility model are:

[0017] First, the foot pad structure of the mouse bottom plate of the utility model is compared with the structure and layout of the foot pad of the traditional mouse bottom plate. The foot pad is installed at the bottom of the connecting plate, and the foot pad can be divided into three areas. By limiting the size and position of the area, the size and distribution of the mouse foot pad are strictly limited, so that when the flatness of the working surface or the mouse bottom plate is insufficient and the contact point between the mouse and the working surface changes during use, the resistance center of the bottom of the mouse still maintains a small offset amplitude, which can reduce the change of resistance feedback during the movement of the mouse, and the operation is light and flexible;

[0018] Second, in a preferred implementation, the mouse sole plate foot pad structure of the utility model has three points on the outer contour of the bottom surface projection of the connecting plate. By expanding the ratio of the area of ​​the triangle formed by the lines connecting the three points to the outer contour area of ​​the bottom surface projection of the connecting plate, the stability of the mouse supported by the area near the three points during movement can be improved, the turning moment during the movement of the mouse can be resisted, and the weakening of the stability of the mouse during movement due to the limitation of the size and distribution of the mouse foot pad can be offset;

[0019] Third, in a preferred implementation, an opening is provided on the connection plate of the utility model for the mouse displacement sensor to receive optical energy so as to work normally. When the mouse moves, the optical sensor can capture the light changes to ensure the normal operation of the mouse;

[0020] Fourth, in the preferred implementation, the plurality of mounting holes distributed on the bottom of the connecting plate of the utility model can adapt to the installation of mouse bodies of different specifications, and has high versatility. BRIEF DESCRIPTION OF THE DRAWINGS

If the drawings are different, the corresponding positional relationships may also change accordingly, so they cannot be understood as limiting the scope of protection.

[0034] In this application, the terms "install", "connected", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, or mutual communication, a direct connection, or an indirect connection through an intermediate medium, the internal connection of two components, or the interaction relationship between two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] Refer to the instruction manual Figure 1-2 The utility model provides a bottom plate foot pad structure, including a connecting plate 1. The connecting plate 1 has a stable structure extending outward, a mouse is installed on the top of the connecting plate 1, and an area for installing the foot pad is provided at the bottom of the connecting plate 1; an opening is provided on the connecting plate 1 for the mouse displacement sensor to receive optical energy so as to work normally.

[0036] There are three points on the outer contour of the bottom projection of the connecting plate 1, at least one of which is located on the outer contour of the bottom projection of the stable structure of the connecting plate 1. The positions of the three points are used to constrain the shape of the bottom surface of the connecting plate 1, and the ratio of the area of ​​the triangle formed by the lines connecting the three points to the outer contour area of ​​the bottom projection of the connecting plate 1 is greater than 0.5.

[0037] The base plate foot pad structure also includes a foot pad set, which is installed at the bottom of the connecting plate, and the bottom of the foot pad set contacts the working surface. There are multiple foot pad sets, each of which has one or more continuous or discontinuous foot pads 2; the bottom of the connecting plate has multiple support areas, and the rectangle with the smallest area of ​​the bottom surface projection of all the foot pads in the foot pad set is the support area of ​​the foot pad set; the bottom of the connecting plate has three mutually exclusive foot pad sets, each foot pad set corresponds to one support area, and the circular area with a radius of 30 mm with the aforementioned three points as the center is called the edge area; the three support areas intersect with the three edge areas respectively.

[0038] by Figure 3 As shown in the figure, for example, a rectangular area represents the support area of ​​a foot pad set, and a circle, oval or other irregular shape in the rectangular area represents a foot pad 2. Figure 3 Parts (a), (b), and (c) are examples of the layout of the foot pad 2 in different support areas. Figure 3 Part (a) in the figure shows that there are three discontinuous foot pads 2 in the support area. Figure 3Part (b) shows that there is only one foot pad 2 in the support area. Figure 3 Part (c) shows that there are two continuous foot pads 2 in the support area, and each foot pad 2 is tangent to the edge of the support area to obtain a minimum rectangular area.

[0039] by Figure 4 As shown in the example, Figure 4 A, B, and C in the figure represent three points on the outer contour of the bottom projection of the connecting plate 1, respectively. These three points constrain the shape of the bottom surface of the connecting plate 1. The rectangular shaded parts represent three supporting areas. The three supporting areas have one or more continuous or discontinuous foot pads 2. The edge areas are set with points A, B, and C as the center and a certain length as the radius, and the edge areas intersect with the supporting areas, so that the foot pads 2 in the supporting areas are as close to the corresponding points A, B, and C as possible, so that the foot pads 2 are arranged at the best position at the bottom of the connecting plate 1 to ensure the stability of the mouse movement.

[0040] The size of each support area is less than 30 mm×30 mm. Preferably, the size of each support area is less than 20 mm×20 mm.

[0041] Preferably, the foot pad 2 is made of wear-resistant and smooth material, such as Teflon or ceramic material.

[0042] Preferably, there are 3 points on the outer contour of the bottom surface projection of the connecting plate 1, and the ratio of the area of ​​the triangle formed by the lines connecting the 3 points to the outer contour area of ​​the bottom surface projection of the connecting plate 1 is greater than 0.7. Furthermore, there are 3 points on the outer contour of the bottom surface projection of the connecting plate 1, and the ratio of the area of ​​the triangle formed by the lines connecting the 3 points to the outer contour area of ​​the bottom surface projection of the connecting plate 1 is greater than 1.

[0043] The foot pad area at the bottom of the connecting plate 1 adopts a groove design, and the foot pad 2 is embedded in the groove. The thickness of the foot pad 2 is greater than the depth of the groove.

[0044] Preferably, the depth of the groove is 0.3 mm, and the thickness of the foot pad 2 is 0.3-0.7 mm greater than the depth of the groove.

[0045] In this embodiment, the groove is a circular groove with a size of 8mm×8mm and a depth of 0.3mm. The area of ​​the foot pad 2 matches the area of ​​the groove and the thickness of the foot pad 2 is 0.6mm. The groove can also be a rounded rectangular groove or other structural grooves.

[0046] The connecting plate 1 comprises a plurality of mounting holes 10 , which are distributed at corresponding positions of the connecting plate 1 and are used for mounting a mouse.

[0047] Refer to the instruction manual Figure 5-6The utility model also provides a mouse, which includes the above-mentioned bottom plate foot pad structure and a mouse body 3. The bottom of the mouse body 3 has a threaded hole matching the mounting hole 10 of the connecting plate 1, and is connected to the threaded hole of the mouse body 3 by a bolt passing through the mounting hole 10 along the bottom of the connecting plate 1.

[0048] The plurality of mounting holes 10 distributed on the connecting plate 1 can be adapted to the installation of mouse bodies 3 of different specifications, and has good versatility.

[0049] The following compares the shapes and layouts of two traditional mouse feet with the shape and layout of the mouse feet of the present invention, illustrating that the mouse feet of the present invention can effectively reduce the variation range of the mouse resistance center.

[0050] Refer to the instruction manual Figure 7 , Figure 7 Parts (a) and (b) are schematic diagrams of the shapes and layouts of two traditional mouse foot pads. Figure 7 Part (a) in the figure is layout 1. The mouse base of layout 1 generally has at least 4 support points (i.e., independent foot pads). The foot pads at each support point are usually small in size. Since the mouse base will deform during injection molding or other molding processes, the base is not an absolute plane. At the same time, due to process limitations, the working surface of the mouse is not an absolute plane, and the height and curvature of the working surface usually vary slightly. Therefore, in the actual use of the mouse, it is a low-probability event that the four support points maintain contact with the working surface at the same time. The absolute majority of working conditions in actual use are that one support point of the mouse base is randomly suspended in the air. Figure 7 Part (b) in the figure is layout 2. The mouse base of layout 2 is more common in gaming mice, and its base generally contains two large-area foot pads. However, in actual use, due to the deformation of the mouse base during injection molding or other molding processes, and the uneven thickness caused by the cutting process of the foot pads, the foot pads still cannot completely fit with the work surface. Partial fit and partial suspension still occupy the vast majority of working conditions, and the part that may fit is generally located near the two sides of the mouse, which can also be proved by checking the wear of the foot pads after use.

[0051] Figure 8 and Fig. 9 The following are schematic diagrams of the changes in the center of resistance of these two traditional mouse foot pad layouts. Figure 8 , Figure 8Parts (a1) and (a2) in the figure show the working condition in which support point A and support point B are in contact with the working surface, and one of support point C and support point D is suspended. When support point D is suspended and support point ABC is in contact with the working surface, the center of resistance when the mouse moves is within the triangular area formed by the three points ABC. According to the change of the load on the three points ABC, the center of resistance moves within area 1 near the center point of triangle ABC. When support point C is suspended and support point ABD is in contact with the working surface, the center of resistance when the mouse moves is within the triangular area formed by the three points ABD. According to the change of the load on the three points ABD, the center of resistance moves within area 2 near the center point of triangle ABD. Therefore, when the support point changes from support point C to support point D during the movement of the mouse, the center of resistance will change from area 1 to area 2, resulting in a large offset. Fig. 9 ,and Figure 8 approximate, Fig. 9 Parts (b1) and (b2) in the figure show the change of the resistance center when the support area A and support area B are in contact with the work surface and support area C or support area D is suspended in the air in the area covered by the two large foot pads. When the support point changes from support area C to support area D, the resistance center will change from area 1 to area 2, resulting in a large offset. The traditional mouse foot pad structure and layout will make the mouse operation process uneven and have poor stability.

[0052] Fig.10 The mouse foot pad of the utility model limits the arrangement area of ​​the foot pad to 3, so that even if there is a deviation in the flatness of the mouse bottom plate and the working surface, and the contact point changes during use, the center of resistance still maintains a small offset amplitude, which can reduce the change amount of resistance feedback during the movement of the mouse. Fig.10 As shown in parts (c1) and (c2) of the figure, the center of resistance of the mouse foot pad and the work surface at two different specific contact positions changes very little. At the same time, by increasing the ratio of the area of ​​the triangle with the three points on the outer contour of the bottom projection as vertices to the outer contour area of ​​the bottom projection, the stability of the mouse during movement can be improved to resist the flipping torque during the movement of the mouse.

[0053] Since traditional foot pads cover a large size and a large number, and the contact surface of the bottom of the mouse is not an absolutely flat surface, the resistance center of the mouse will change greatly during movement. By adopting the structure of this embodiment to limit the foot pad arrangement area to 3, the variation range of the mouse resistance center can be effectively reduced, making the mouse operation process smooth and responsive.

[0054] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
